Abstract

L'invention concerne une section en labyrinthe pour une pompe submersible, comprenant un boîtier externe ayant un accouplement en prise étanche au niveau de chaque extrémité longitudinale du boîtier externe. Un tube interne est en prise étanche au niveau de chaque extrémité avec l'un des accouplements pour délimiter un espace annulaire étanche. Une pluralité de sections de tube à labyrinthe sont disposées dans l'espace annulaire, chacune comprenant des tubes à labyrinthe en prise avec des plaques d'extrémité. Une pluralité de sections de tube à labyrinthe permettent le déplacement de fluide à travers les tubes à labyrinthe, des espaces externes aux tubes au labyrinthe et entre les plaques d'extrémité pour remplir l'espace annulaire. L'une des sections de tube à labyrinthe contraint le fluide à se déplacer uniquement à l'intérieur des tubes à labyrinthe, le tube interne entre les plaques d'extrémité dudit tube à labyrinthe comprenant un orifice pour fluide à l'intérieur du tube interne.
